I haven't been bothered to read the last 11 pages so sorry if I say anything that's already been said

But I may as well just give you the whole view.
Got the game yesterday, played quite a lot of it as you might imagine, both against the CPU and human opponents. I've used the national teams and club teams.
The mix between making the game fresh and new but not losing the standard set in PES3/WE8 is perfect. It feels similar but diferent at the same time. Love the new passing, holding down X for longer (or triangle for through passes) makes the ball go to a player further away, pretty much like a power bar for passes. Crossing is improved too.
Dribbling is different now also. Stepovers and 360's actually have an effect on the opponent now. Do a couple of stepovers and press R1 and chances are you'll leave your opponent standing. Looks ace as well
From what I've noticed, shots can curl in open play although there's no way of controling it. Shots also dip if hit from distance with high power bar.
Other new things include a neat lay off which can be done by pressing X and a direction as the ball is dropping to you.
Edit mode is amazing, you can change almost anything on the players body, you can change shoulder width, chest size, stomach size, legs size, arms, you name it! There's also the face editor from last years game, which has been re-vamped and features a few new possibilities. Things which were previously grouped together (eyes and eyebrows for example) are now seperate and therefore more combinations are possible. The same system works with hairstyles. You choose a base style, then choose the fringe, bottom back, and thickness/volume etc.
Seen some comments about nets and net physics on the forums before, well, the net physics are fantastic! A lot better than last years, they now seem to have more 'give' in them, if you hit a hard shot the net will bulge more, as it should. There are also green nets in a couple of stadiums! Also a few different styles from previous years.
Haven't been able to try master league yet because of the language, I think I'll wait for an english patch before trying that. Looks very thorough though.
I will report back when I have played more
